Asymmetrical nose and nostril... how to correct them without surgery? (Photo)

Recently i noticed that i have an asymmetrical nose and it could be because of my asymmetrical nostrils. I really want to correct them without any surgery. Please help with this. One thing i want to add that this asymmetry has occurred from 1-2 years before this i had perfectly symmetrical nose. Previous to this i never had major nose injury or any surgery.
